Filter by:This is a Phase 2, open-label, multicenter, study to evaluate safety, tolerability and efficacy of SAR442501 in children from birth up to 12 years of age with Achondroplasia.
The goal of this observational study is to characterize the epidemiology and natural history of MPS diseases by building a retrospective and prospective collection of extensive phenotypic data from French MPS patients.
This is a Phase I/II, single arm, open label study of vosoritide therapy provided subcutaneously at 15 ug/kg/day for 48 weeks to 6 patients with MPS IVA or VI. Prior to enrollment in the interventional arm of study, subjects will be followed for a minimum of 24 weeks to gather information on safety profiles and determine annualized growth velocity. The primary study endpoint is the determination of safety and tolerability of daily vosoritide treatment in MPS. Exploratory endpoints include changes in linear and segmental growth as well as biomarkers of growth and bone metabolism.
Newborn screening (NBS) is a global initiative of systematic testing at birth to identify babies with pre-defined severe but treatable conditions. With a simple blood test, rare genetic conditions can be easily detected, and the early start of transformative treatment will help avoid severe disabilities and increase the quality of life. Baby Detect Project is an innovative NBS program using a panel of target sequencing that aims to identify 126 treatable severe early onset genetic diseases at birth caused by 361 genes. The list of diseases has been established in close collaboration with the Paediatricians of the University Hospital in Liege. The investigators use dedicated dried blood spots collected between the first day and 28 days of life of babies, after a consent sign by parents.
This is an international prospective and retrospective registry of patients with Lysosomal Storage Diseases (LSDs) to understand the natural history of the disease and the outcomes of fetal therapies, with the overall goal of improving the prenatal management of patients with LSDs.
Morquio A disease is a devastating systemic skeletal disease in which detailed progression and pathogenesis remain unknown. The proposed project aims to establish a non-invasive objective assessment that can be applicable to all ages of patients to better understand the progress of their disease and the most serious clinical problems (cervical instability and stenosis, tracheal obstruction, hyperlaxity of joints, hip dysplasia, and small lung capacity). The outcome of this project will lead to a more precise understanding of the skeletal/pulmonary compromise and defining clinical endpoints in this disease for future clinical trials of current or developing therapies.
The clinical project "Eight At One Stroke: Attention Gangliosidoses" represents a clinical registry for recording the clinical manifestation and the disease progression of gangliosidoses. The intention of this project is to better understand the manifestation and progression of gangliosidoses and to raise awareness of these disorders in the public health service. The patients or their families, respectively, will be integrated in the study in order to measure Patient Outcome and to objectify the psychosocial burden for the patient and his family. The study has a retrospective and a prospective part. It is planned to transfer the data of the study into a continuous registry.
The purpose of this study is to understand the course of rare genetic disorders that affect the brain. This data is being analyzed to gain a better understanding of the progression of the rare neurodegenerative disorders and the effects of interventions.
Mucopolysaccharidosis IVA (MPS IVA) (or Morquio A disease) is a rare recessive autosomal lysosomal storage disorder caused by deficiency of N-acetylgalactosamine-6-sulfatase (GALNS) resulting in accumulation of the glycosaminoglycans (GAGs) chondroitin-6-sulfate and keratin sulfate (KS). Patients display progressive development of skeletal and joint abnormalities and non-skeletal features including respiratory, cardiac, sensorial and neurological complications. Recently, a specific treatment using enzyme replacement therapy (ERT) with recombinant human GALNS (elosulfase alfa) has become available. A multicenter double-blind placebo-controlled phase 3 trial (176 patients, age > 5 yrs) showed significant improvement in endurance of 22.5 m in 6 Minute Walking Test (6MWT) distance after 24 weeks of treatment with elosulfase alfa at 2.0 mg/kg/week as compared with placebo group. In addition to ERT, a multidisciplinary management approach is necessary for coordinating assessment and follow-up as well as for providing individualized supportive and symptomatic care. The clinical presentation is highly variable from one patient to another regarding age at onset, severity, progression rate and life expectancy. Most patients are affected with the classical phenotype characterized by short trunk dwarfism with short neck and adult height < 1 m. Atypical phenotypes with less severe extension of skeletal manifestations, adult height > 1m, and less frequent complications in other organs have been progressively recognized. Clinical management differs depending on the clinical presentation of the patients but natural history of the disease is largely unknown in atypical phenotypes. Precise and exhaustive follow-up data are needed in such patients to increase our knowledge of this natural history and to define the best criteria to evaluate ERT efficiency. The investigators propose a prospective clinical study focused on a unique large series of 9 adult patients (aged from 18 to 55 years) followed in a single expert center for metabolic disorders located at the university hospital of Bordeaux, France. Eight of these patients are affected with atypical MPS IVA characterized by less severe evolution of the disease and heights ranging from 135 to 176 cm (the last patient height is 102 cm). Investigators aim to increase knowledge on the natural history of the disease in adult patients with atypical MPS IVA, treated or not with ERT, and to develop new objective and robust clinical criteria to evaluate the efficiency of ERT over time, particularly in patients presenting an atypical phenotype. The entire cohort treated or not treated with ERT, will be evaluated at baseline and every year during a 5-years period. The complete evaluation at baseline will be our absolute priority as well as obtaining long-term and exhaustive follow up of the patients treated with ERT (two patients of the cohort already treated, and ERT expected in three additional patients in the next months). The investigators designed a schedule of systematic and exhaustive assessments based on the recommended follow up from experts panel consensus meeting (MorCAP protocol) extended to some additional investigations including motor, cardiac and rheumatologic exams as our specific focus.
